I remember watching Plague's XCOM 2 stream and at one point he just stopped, sighed, and said that the DS3 LP was going to be a mess because of Pat passing off his wonky interpretation of lore and characters to Woolie and Matt, neither of whom know close to enough to challenge him. I thought it was hilarious at the time because he just threw Pat under the bus as a team leader for the LP; I'm starting to realize Plague was being dead serious and not at all trying to be amusing.
Pat isn't ruffling my feathers just yet, though. The LP is still gold and it better stay that way.
I did think it was weird that Matt came up with a plausible idea about Siegward being a descendant and Pat just instantly shut him down. Not even a "perhaps", or a "I don't know if I agree with that", just "No". I chalked that up to Pat being allergic to opinions that differ from his own, but if I were Matt, I'd expect a follow-up explanation as to why the answer is no, instead of being left hanging.
